Gnat (likely a Fungus Gnat)

Damp, moist environments, often associated with decaying organic matter, fungi, and potted plants (indoors).

Larvae feed on fungi, decaying plant matter, and sometimes plant roots. Adults generally do not feed or feed on liquids such as nectar.

Adults are weak, erratic fliers and are attracted to light and moisture. Females lay eggs in moist soil or decaying organic matter. Larvae are found in the substrate. Life cycle is relatively short, leading to rapid population growth under ideal conditions.

Potential risks include being a nuisance pest indoors, especially to houseplants, as large numbers of larvae can damage roots. Generally not harmful to humans. Benefits include decomposing organic matter and serving as a food source for other organisms in their natural habitat.
